The development of activator of to decoke of hydrogenation of FH-UDS derv deepne
From;    Author:Stand originally
Recently, by stroke grind the courtyard, refine that press down the sea changes company of branch, luxuriant v/arc a person's status, Qi Lu 7 units such as petrifaction of branch, Jin Ling branch, Shanghai and company of Luoyang petrifaction engineering assume jointly " activator of to decoke of hydrogenation of FH-UDS derv deepness.

Activator of to decoke of hydrogenation of FH-UDS derv deepness is carrier with the alumina of compound auxiliary modified, it is active group with W-Mo-Ni-Co yuan, kong Rong is big, taller than expressing an area, mechanical intensity is high, have a metal to spend center of active of tall, edge dispersedly many wait for a characteristic, raised active of hydrogenation to decoke thereby. This activator processes straight heat up in a steamer or fabricating diesel oil below condition of low, middling pressure, all have the exceedingly good hydrogenation to decoke, active that take off nitrogen and good stability, strong to raw material adaptability, can produce sulfur content to satisfy Europe Ⅲ and Europe Ⅳ to discharge the derv constituent that the standard asks. Production of this activator batch, application makes clear as a result, preparation craft is feasible, product quality is stable, without requirement of special environmental protection, already filed Chinese patent.

FH-UDS activator changes a branch in the refine that press down the sea respectively 2 million tons / year with company of luxuriant v/arc a person's status 2.6 million tons / year application of industry of derv hydrogenation unit makes clear as a result: In certain hydrogen airspeed of cent pressing, bulk, reaction oily volume of lukewarm, hydrogen falls than waiting for a condition, derv of treatment catalysis derv, straight heat up in a steamer and cooking gas blend raw material, the clean derv constituent that can produce sulfur content to be less than 50 μ G/g (desulphurization is led 99.6% ) .

FH-UDS activator applies 2.6 million tons at company of luxuriant v/arc a person's status / year in derv hydrogenation device, react in hydrogen the condition such as 360 ℃ issues temperature 1.54h-1 of airspeed of cent pressing 5.9MPa, bulk, on average, machine derv of straight heat up in a steamer and catalytic derv miscella, via 24 hours of assessment, can produce G/g of μ of sulfur content <10 exceed low sulfur derv.

Expert attending the meeting thinks: Active of activator of to decoke of hydrogenation of FH-UDS activator deepness is good, industrial application obtains satisfactory result, function of this activator whole reached the advanced level of domain of hydrogenation of current international derv, the proposal popularizes application further.
